preparation example Construction

[0029] A preparation method for waste water treatment preparation, comprising the steps of:

[0030] Step I: activation of persulfate, using metal ions to activate persulfate to obtain activated persulfate; persulfate is sodium persulfate or potassium persulfate, and the metal ion is Cu 2+ 、Ag + 、Co 2+ At least one of them; the pH of the activation treatment is 7-9;

[0031] Step II: Preparation of composite bacterial agent, after separately cultivating Bacillus, Pseudomonas putida, Candida, nitrosifying bacteria, nitrifying bacteria and denitrifying bacteria, mix in proportion to obtain composite microbial bacterial agent, and then compound The microbial bacterial agent is mixed with the carrier in a mass ratio of 1:2 to obtain a composite microbial agent;

[0032] Step III: Mix stearoyl glutamate, glucose, silica gel powder, activated persulfate, polyvinylpyrrolidone, and compound bacterial agent in proportion, and adjust the pH of the system to 5.3-8.1;

[0033] Step IV...

Embodiment 1

[0039] A wastewater treatment preparation, comprising the following raw materials in parts by mass: 15 parts of stearoyl glutamate, 12 parts of glucose, 12 parts of silica gel powder, 4 parts of persulfate, 3 parts of polyvinylpyrrolidone, and 25 parts of composite bacterial agent; The persulfate is activated by metal ions; the composite microbial agent includes a carrier and a composite microbial agent, and the composite microbial agent includes 5 parts of Bacillus, 3 parts of Pseudomonas putida, 8 parts of Candida, and 3 parts of nitrosative bacteria , 3 parts of nitrifying bacteria, and 5 parts of denitrifying bacteria; the carrier is diatomite, activated carbon and peat soil mixed according to the mass ratio of 1:3, and the mass ratio of the carrier to the composite microbial preparation is 2:1.

[0040] In the present embodiment, the persulfate is potassium persulfate (PMS), and the metal ion is Co 2+ , and the concentration ratio of persulfate to metal ion is 5:1. In add...

experiment example 1

[0046] Experimental Example 1: The effect of persulfate activation on the degradation rate of p-aniline, ammonia nitrogen degradation rate and TOC removal rate

[0047] experimental method:

[0048] 1. Degradation rate of aniline: the concentration of aniline is measured by liquid chromatography, and the calculation method of the degradation rate of aniline is:

[0049] B(%)=C 0 -C 1 / C 0 ×100%

[0050] Wherein, B represents the degradation rate of aniline; C 0 Indicates the initial concentration of aniline; C 1 Indicates the concentration of aniline after degradation.

[0051] 2. Ammonia nitrogen degradation rate: Nessler's reagent colorimetric method is used for ammonia nitrogen concentration, and the calculation method of ammonia nitrogen degradation rate is:

[0052] N(%)=C 0 -C 1 / C 0 ×100%

[0053] Wherein, N represents the degradation rate of ammonia nitrogen; C 0 Indicates the initial concentration of ammonia nitrogen; C 1 Indicates the concentration of am...

Abstract

The invention relates to the field of sewage treatment, and discloses a wastewater treatment preparation and a preparation method thereof.The wastewater treatment preparation is prepared from, by mass, 12-15 parts of stearoyl glutamate, 10-15 parts of glucose, 15-20 parts of silica gel powder, 3-5 parts of persulfate, 1-5 parts of polyvinylpyrrolidone and 10-30 parts of complex microbial inoculants; the persulfate is subjected to metal ion activation treatment; the composite microbial agent comprises a carrier and a composite microbial agent, wherein the composite microbial agent comprises 3-5 parts of bacillus, 3-5 parts of pseudomonas putida, 5-10 parts of candida mycoderma bacteria, 1-3 parts of nitrosobacteria, 3-5 parts of nitrifying bacteria and 1-5 parts of denitrifying bacteria. The method provided by the invention has an outstanding degradation effect on aniline in wastewater, has excellent flocculation and ammonia nitrogen degradation effects, and has very high popularization and application values.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a waste water treatment preparation and a preparation method thereof. Background technique [0002] Aniline, also known as Anilin, Anilin Oil, Aminobenzene, has a molecular formula of C 6 H 7 N, a colorless oily liquid, is one of the most important amine substances, widely used in rubber, medicine, organic resin, paint, leather, petroleum processing, plastics, antioxidants and other chemical industries. Aniline itself can also be used as a black dye, and its derivative methyl orange can be used as an indicator for acid-base titration. Due to the toxicity of anilines to ecological organisms and their potential carcinogenicity, my country has included them in the list of environmental priority control pollutants as early as 1989. With the increasing development of the chemical industry and the continuous advancement of science and technology, for the consideration of environmenta...
